Publication number: 20200029273Abstract: In a communication system (1), when there is no access destination corresponding to a service type to be used by a piece of UE (50) in one of cellular communication and non-cellular communication, a retrieval unit (13) of a DB server (10) selects an access destination by referring to correspondence information in the other of the cellular communication and the non-cellular communication. Thus, when there is no access destination corresponding to the service type to be used by the UE (50) in one of the cellular communication and the non-cellular communication, the access destination corresponding to the service type is selected in the other of the cellular communication and the non-cellular communication. Therefore, it is possible to select an access destination suitable for the service type from both the cellular communication and the non-cellular communication.Type: ApplicationFiled: September 20, 2017Publication date: January 23, 2020Applicant: NTT DOCOMO, INC.Inventors: Takuya Shimojou, Masayoshi Shimizu, Daisuke Nojima, Akira Yamada, Shigeru Iwashina

Publication number: 20190032621Abstract: A control apparatus controls the operation of a starter such that, after an idling stop is executed and before a request for starting an engine is subsequently issued, the control apparatus executes a preset which causes a pinion to engage a ring gear. A control apparatus controls the operation of a starter such that, after an idling stop is executed and before a request for starting an engine is subsequently issued, the control apparatus executes a preset which causes a pinion to engage a ring gear. It is determined that the preset condition has been cancelled, and the preset is again executed. In that case, the pinion is already engaged with the ring gear at the time point when a request for starting the engine is issued. In that way it is unnecessary for the control apparatus to push out the pinion after a start request is issued.Type: ApplicationFiled: January 25, 2017Publication date: January 31, 2019Applicant: DENSO CORPORATIONInventors: Yoshitomo TAKEUCHI, Atsuyuki HIRUMA, Akira YAMADA, Akihiro IMURA, Takuro NAKAOKA
